some picture updates, photos taken 8/30/15.
FHN's Musa 'Goldfinger,' same plant pictured above but about 2 weeks later, acclimated to outdoor/full sun conditions.  These really grow quickly once you harden them off:
 
Greenearth Publishing's "california gold" which many suspect isn't the real deal:
 
Greenearth's Musa 'Ice Cream,' which is growing very slowly, maybe because the corm wasn't planted at the proper depth:
 
Here's what was sold to me as "veinte Cohol" @ a local farmer's market, but turns out it's likely Hi color mini.  Check out the wine marks on the water sprout's leaves.  This is also a pretty slow grower:
 
And a group shot.  The 2 bigger plants near the bottom of the steps are rajapuri (edit

lant flowered in July, verified not rajapuri.  Still don't know what it is).  Now those have grown crazy fast, almost doubling in size in about a month:
